MICHAEL RUNSTETLER, OF DAYTON, OHIO, ASSIGNOR TO FARMERS FRIEND MANUFACTURING COMPANY, OF SAME PLACE.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 226,115, dated March 30, 1880.

Application filed January 10, 1880.

To all whom it may concern Be it known that 1, MICHAEL RUNSTETLER, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Corn-Planters, and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification, in which- Figure 1 is a top plan of the bottom of a seed-box with the box, the cap which covers the seed-cup wheel, and the cut-off removed. Fig. 2 is the same plan as Fig. 1, except that the outer ring of the seed-cup wheel is removed. Fig. 3 is the same plan as Fig. 2, showing the central part of the seed-cup wheel removed. Fig. 4. is a top plan of the slide and the pawls which it carries. Fig. 5 is a perspective View, bottom side upward, of the entire seedcup wheel. Fig. 6 is a perspective view of the outer annular part of the seed-cup wheel. Fig. 7 is a perspective view of the central part, of the seed-cup wheel. Fig. 8 is a sectional elevation in the line a0 :0 in Fig. 1. Fig. 9 is a sectional elevation through the pawlpivot and stop in the line y y in Fig. 1.

This invention relates to corn-planter seedmeasuring devices of that class in which an intermittingly-rotating seed-cup wheel is used with seed-cups through said wheel or disk; and the'invention relates to improvements in the construction of the seed-cup wheel and other parts, and to combinations hereinafter described, and set forth in the claims hereto annexed.

Referring to the drawings by letters, letter Arepresents the bottom of a seed-box, and B a slide, arranged to reciprocate in an ordinary median groove in the bottom A, the extent of its motions or throws being limited by the ends of a slot, b, cut in an extension, I), of one of its sides, coming in contact with the outer walls of the opening 0, which leads to the tube or conductor which conveys the seed 5 of the drawings.

to the ground. "The outer side of the extension 11 is provided with lugs on its under side (shown by dotted lines at Fig. 4 of the drawings) for giving motion to the ordinary discharging-valve in the seed-tube. (Not shown in the drawings.)

The slide B has a slot, b, through which a stud, D, with a shoulder, d, projects upwardly from the central part of the bottom plate, A.

E is an annular plate or ring, flat on its upper side, and fixed in position by standards e, which extend upward from the base A, and has an opening, 0, immediately over the opening 0 which leads to the ordinary conductor-tube, for conveying the seed to the soil.

Theseed-cup wheel F is formed of two parts- 6 5 a'central disk or plate,F, and an outer annular plate, F". The disk F has a central hole, f, by means of which it may be placed to rotate on the stud D as a journal, with the boss f,

which projects from its lower side, resting on the shoulder (1. Lugs f project laterally and radially from the disk F, and pendent lugs Gr project downward from its under side. The lugs G each have a flat side, g, and a rounded or convex side, 9, as shown in Fig. 5 of the drawings. There may be any desired number of the lugs f but the numberof lugs Gshould be equal to one-half the number of discharges of seed made by the seed-cup wheel in a complete rotation on its axis.

The annular plate F has seed-cup holes f through it, and, to give them sufficientdepth with lightness of plate, an ordinary annular flange, f, projects downward from and surrounding each seed-cup hole, as shown at Fig.

The disk or plate F is large enough to close the central opening of the plate F when said plate F is placed thereon, and each of the radial lugs f rests between two flanges, f, as shown at Fig. 5 0 of the drawings, and thus hold the disk F and annular plate F, so that they will rotate together, and so that the plate F may be removed without removing the disk F when it is desired to substitute another plate, F with 5 seed-cups of greater or lesser capacity, and

. pawls H H.

also providing; for snbstitutive disks F, when required, without changing the attendant plate F.

With a seed-cup plate thus constructed in two parts, F F, sets of plates F, with seedcups of different capacities, may be furnished with each machine without the ordinary expense of finishing with each part F the lugs by which they receive motion from the slide.

The slot b divides the slide B into two limbs, b. H H are pawls, formed as shown more plainly at Fig. 4 of the drawings, with one end, it, preferably formed concave at its extremity, and their other end formed with an inclined face or cam, it.

Each pawl H H has a side projection, h. The pawls H H are centrally pivoted one to each limb b of the slide and at opposite ends thereof. The pivot I of the pawls may be formed as plainly shown at Fig. 9 of the drawings, or in any other desirable manner. The outer end of each pawl carries a downwardlyprojecting lug, J, which moves in a slot, j, in the slide B when the pawl is oscillated, and thus limits the extent of oscillation of the (See full lines at Fig. 9 and dotted lines at Fig. 4. of the drawings.)

J J are cam-lugs projecting upwardly from the base A through the .slot 1) in the slide, one in close proximity to the cam-face h of each pawl H H.

The pawls H H are below the annular plate E, and the lugs G project downwardly through the plate E into the same horizontal plane as said pawls.

The seed-boxes containing the dropping devices may be fixed on the planter as desired, and the slide B may be reciprocated in any ordinary or desired manner.

At Fig. 1 of the drawings the slide B is shown as having completed its throw in the direction of the arrow or to the left hand. In making this throw the forward concave end of the pawl H came in contact with the rounded or convex side 9 of one of the lugs G, and thus gave a partial rotation to the seed-cup wheel, and brought a seed-cup to register with and discharge its seed through the opening 0, and as the pawl H advanced toward the lug G, upon which it acted, its cam-face h was released from thelng J, and the pawl thereby allowed to swing or oscillate slightly outward at its forward end while in contact with and while moving the lug G forward, thus producing a rolling contact between the contact-surfaces of the pawl H and the lug G on which it acts, and thus reducing the friction between these parts to the minimum and preventing the great wear which occurs when these parts slide on each other.

It will be seen that the projection h on the pawl H, at the end of the throw of the slide to the left hand, came in contact with the flat side 1 of the lug G next succeeding the one on which said pawl acted, and thus arrested the forward movement of the seed-plate F at the proper position to dischargclai The movement of the slide to the left handpis described, brought the cam-face h of the pawl II in contact with the adjacent lug J, and thus oscillated or swung the pawl H sea as to bring its forward end inward and read' mto act'on a lug, G, when the slide is moved toward the right hand, and thus give another-partial rotation to the seed-cup wheel in then'ame manner as given by the pawl H, hereinbefore described.

In moving the slide toward the right hand the lug J will strike the cam-face h of the pawl H and oscillate or swing it to the position shown by full lines at pawl Hand by dotted lines at pawl H, (see Fig. 4 of the drawings,) and ready for another forward movement to the left hand, as hereinbefore described.

The pawls H H, pivoted as described, cannot lock with the lugs G if the slide is stopped and returned from a half'stroke, as sometimes occurs.

What I claim as new, and desire to secure by Letters Patent, is

1. In a corn-planting machine, a seed-cup wheel constructed of two parts, an inner central part carrying pendent lugs, which are acted on by pawls on the slide or other d 'wices, in combination with an outer part, F, having seed-cups through it, adapted for substitution of either part without changing the other part, substantially as and for the purpose specified.

In a corn-planting machine, a seed-cup wheel constructed of two parts, an inner central part, F, carrying lugs, which are acted on by the slide, in combination with an outer annular part, F, having seed-cups through it, and projections adapted to receive radial lugs f, which project from the central part, F, for securing the two parts of the seed-cup wheel to each other, substantially as described, and for the purpose specified.
